Abstract

Reservoirs in beach area are of multiple types and vary laterally.Few drilled holes bring difficulties to acquire and collect all kinds of data.Here we use Chenghai oilfield as the example.The seismic data were used to develop the large range stratigraphic correlation of long displacement horizontal wells and setup the stratigraphic and structural model.We also set up the lithofacies model of reservoirs by means of constraint of seismic inversion data, and make the modeling of reservoir parameters based on the lithofacies model.We use the 3D geological model to extract the electric log of planed wells for the optimization of well location, field trace and optimization of development plan, therefore minimize the risk in the deliverability building.The result is positive in field operation.

Key words： Chenghai oilfield; Seismic inversion; Time-depth conversion; Geological modeling.
